Solved Random reboot

[HornetMaX]

Hi all,
back home after 3 months, started the PC, everything fine.
Updated my video drivers (OK) and made all the pending windows updates and .. troubles.

First, the PC started to reboot in the middle of the updates. Selcting only 1-2 updates at a time i managed to complete all of them.

However, now the PC reboots randomly.
It doesn't seem power/temperature related (it doesn't happen while gaming, it seems to happen when idle or with light apps like web browsing). I checked thew ram (memtest86+) and it seems OK.

Notice that almost all the times, it just reboots, no BSOD.

I've attached the screenshot of the event viewer, with the events relative to a single unexpected reboot highlighted in blue.

Any help appreciated !!

Thanks,

MaX.

Hello HornetMax, welcome!
Could you please post full details as explained in this tutorial:

Hi, here are the details.

Thx.

Your dump file points to a driver: LV302V64.sys

It should only be found in the directory:
\SystemRoot\system32\DRIVERS\LV302V64.SYS

If you find it elsewhere (also) then there is a chance that it's a malware infection. In that case do a complete system scan with your (up to date...) Antivirus and use a anti malware tool. Plenty of info on that in this forum.

If only found in the correct (above) directory, try renaming it to LV302V64.SYS.OLD

and reboot.

Thanks for the help. The file is located only at:

- C:\Windows\System32\drivers
- C:\Windows\System32\DriverStore\FileRepository\lpepi64v.inf_amd64_neutral_f339c42a4d192519

I did a full scan with Avira antivirus and Malwarebytes Anti Malware (both updated) first thing after coming home, nothing found.

Should I rename both files in .old ?

MaX.

yes.

Freaky.

I can rename the one in the C:\Windows\System32\drivers directory, but not the one in the C:\Windows\System32\DriverStore\... directory.
I'm prompted for admin rights (i have) but when I click I get a pop-up with the message:

You need permission to perform this action.

You require permission from SYSTEM to make changes to this file.

Only buttons available are "Try again" (useless) and "Cancel".

Might not be a problem. Driverstore should only be a backup off, and by Windows. It's files should not be used except for restoring corrupted files.

If renaming to .old did work for the first one, as it should, reboot and keep fingers crossed...

For extra safety, at the price of a minor discomfort, I'm keeping my balls crossed too

I'll let you know. Out of curiosity, how did you narrow it down to that driver ?

The info in dumpfiles can be read and analysed by using Windows debugging tools.
There are some non MS tools on the market but the standard MS stuff works best in my humble opinion...

But... let's first see if your problem is really solved...

 

[HornetMaX]

Hmmm ... strange stuff going on ...

I renamed the file, rebooted, web-cam was no longer working (seems to indicate the file was what it claimed to be, a driver for the web-cam). Replugged the web-cam, working fine.

However, the random reboots still happens. Even more, sometimes the PC just goes on all by itself at night. :shock:

Most of the time it doesn't event reach the end of the POST, and it shut downs again. Most of the times it repeats this a few times.

When reboot happens in while logged in windows, it's a clean reboot: the apps close, the shutdown message appears, it shuts down properly (no BSOD), then it tries to restart (as described before: POST screen, shutdown, wake-up, POST screen, shut down, ...).

Sounds like an hdw issue, which sucks as the PC is a Dell Dimension 9200 with tons of non-standard parts I can't switch.

If there's anything else I can try just let me know. Otherwise, I'm likely to be ready for a new PC ...

Another thing to try is to check all your powersaving settings. I've noticed more people getting freeze or reboot problems after recent (april - may?) MS updates to W7. I haven't figured out (yet) if there is an exact culprit out there but it doesn't hurt to try, specially in your case as automatic starting up of the machine is also a powersetting thing.

So... try turning off ALL powersaving stuff, not only in your normal powersetting mode under 'advanced settings' but also the specific energy settings on ALL your devices....

if that helps, you can allways turn them on again... one by one and find the one that causes it.

 

[HornetMaX]

HI,

I was already on the "HIgh performance" power setting plan, but I've manually reviewed the advanced settings and put everything to off/never.

One of thismorning's reboot has produced a BSOD with a minidump,
I've attached it, just in case.

[MvdB]

I'll have a look as soon as I can. Just to b4e sure on your energy settings. Below is an example of what you need to check for ALL of your devces. Did you do that or was it just within the powerplan..?

[HornetMaX]

Yeah, I've only checked the power plan.

Now I've also checked in the device manager: I've 7 devices labelled "USB root hub" and all of them have:

- Allow the computer to turn off this device to save power ==> UNCHECKED
- Allow this device to wake the computer ==> UNCHECKED AND GRAYED OUT

I've found my Logitech G500 mouse has the option:

- Allow the computer to turn off this device to save power ==> UNCHECKED AND GRAYED OUT
- Allow this device to wake the computer ==> CHECKED

Same thing, under the keyboard category, I have 2 entries named "HID keyboard" (uh ? normal ?) and one "Microsoft SideWinder X4 keyboard (IntelliType Pro)", all of them with the same settiongs as the mouse.

Nothing else seems to have power management settings.

Ok well done... But please realise my screenprint with the usb devices is only an example. This needs to be done on ALL devices! Not only usb.

+, if you have one... Turn off your smartcard reader. Both in usb as in usb....

I checked all the devices, not only USB ones.

About the smartcard reader, what do you mean with "both in usb as in usb" ?
I have a card reader (SD/SM/XD/MS etc) but it's a dell thing that plugs straight into the motherboard. The devices appea runder the Disk scetion (4 discs, one for each card type). I can easily unplug the cable and see if that helps.

[HornetMaX]

More than 2 days without unexpected reboots / start-ups.

I didn't disable the card reader nor touch the device specific power settings.

It seems the changes I've done in the power management plan are enough to bring the situation back to normal. At leastm I hope so !

Thanks a lot for the help !

Hope it is!! Would be great...

Sorry for not answering your earlier question quicker. I should have said: USB and Drive(s) (i.e. F: SD card, G: Compact Card etc)

But who knows? You might have gotten it... Log or write down what you did for future ref... you never know

 

[HornetMaX]

hmmm... guess i spoke too early ...
Yesterday evening, PC woke up all by itself. Actually, it tried to wake up a few times,
reaching the POST screen and then shutting down. When it finally managed to boot, it went into repair mode (of course). 15min of repair but nothing helpful found.

I'm freakin' confused now: it's not only that sometimes it decides to shut-down ... sometimes it decides to power-on all by itself !!
